The Australian GeoGuides (LR series) are a set of publications intended for property owners; local councils; planning authorities;developers; insurers; lawyers and, in fact, anyone who lives with, or has an interest in, a natural or engineered slope, a cutting, or anexcavation. They are intended to help you understand why slopes and retaining structures can be a hazard and what can be done withappropriate professional advice and local council approval (if required) to remove, reduce, or minimise the risk they represent. TheGeoGuides have been prepared by the Australian Geomechanics Society, a specialist technical society within Engineers Australia, thenational peak body for all engineering disciplines in Australia, whose members are professional geotechnical engineers and engineeringgeologists with a particular interest in ground engineering. The GeoGuides have been funded under the Australian governments’ NationalDisaster Mitigation Program.

LANDSLIDES IN THE COASTAL ENVIRONMENT

Coastal Instability

The coast presents a particularly dynamic environment where change is often the norm. Hazards exist in relation to bothcliffs and sand dunes. The coast is also the most heavily populated part of Australia and always regarded as “prime” realestate, because of the views and access to waterways and beaches.

Waves, wind and salt spray play a significant part, causing dunes to move and cliff-faces to erode well above sea level. Our response is often to try to neutralise theseeffects by doing such things as dumping rock in the sea, building groynes,dredging, or carrying out dune stabilisation. Such works can be very effective, butongoing maintenance is usually needed and total reconstruction may be necessaryafter a relatively short working life.

Of particular significance are extreme events that cause destruction on a scale thatignores our efforts at coastal protection. Records show that cliffs have collapsed,taking with them backyards which had been relied upon as a buffer between ahouse and the ocean. Sand dunes have also been washed away resulting in thedramatic loss of homes and infrastructure. As with most landslide issues, eventhough such events may be infrequent, they could happen tomorrow. It is easy tobe lulled into a false sense of security on a calm day.

In coastal areas, typical landslide hazards (GeoGuides LR1 to LR4) arecompounded by coastal erosion which, over time, undercuts cliffs and eventuallyresults in failure. In the case of sand dunes, dune erosion and dune slumpinghave equally dramatic effects. Coastal locations are subject to particularprocesses relating to fluctuating water tables, inundation under storm tides anddirect wave attack. Large sections of our more sandy coastline are receding underpresent sea conditions. The hazards are progressive and likely to be exacerbatedthrough climate change.

Coastal Development

If you own, or are responsible for, a coastal property it is important that you understand that, where the shore line isreceding, there is a greater landslide risk than would be the case on a similar site inland. The view may make the riskworthwhile, but does not reduce it.

Coastal Landslides

Coastal landslides are little different from other landslides in that the signs of failure (GeoGuides LR2) and the causes(LR3, LR4 & LR5) are largely the same. The main difference relates to the overriding influence of wave impact, tidalmovement, salt spray and high winds.

Cliff failures

In addition to the processes that produce cliff instability on inland cliffs, coastal cliffs are also subjected to repeated cyclesof wetting and drying which can be accompanied by the expansive effect of salt crystal growth in gaps in the rocks. Theseprocesses accelerate the deterioration of coastal cliffs. At the base of cliffs, direct wave attack and the impact of bouldersmoved by wave action causes undercutting and hence instability of the overall face. Figure 2 of GeoGuide LR4 providesan example. Whilst the processes leading to coastal cliff collapse may take years, failure tends to be catastrophic and withlittle warning. In many cases, waves produced by large oceanic storms are the trigger assisted by rainfall to producecollapse. These are also the conditions in which you are more likely to be inside your home and oblivious to unusualnoises or movements associated with imminent failure.

Sand dune escarpment and slope failures

An understanding of coastal processes is essential whendetermining beach erosion potential. Waves produced by largeoceanic storms can erode beaches and cut escarpments intodunes. These may be of relatively short duration, when beach re-building happens after the storm, but can be a permanent featurewhere long term beach recession is taking place. In manylocations, houses and infrastructure are sited on or immediatelybehind coastal dunes. After an escarpment has eroded, thoseassets may be lost or damaged by subsequent slumping of thedune. It is important that, on erodible coastal soils, the potentialfor landward incursion of an erosion escarpment is determined.Having done this, the likelihood of slope instability can beestablished as part of the landslide risk management process.Injury, death and structural damage have occurred around theAustralian coast from collapsing sand escarpments.

The large scale and potentially high speed of coastal erosion processes means that major civil engineering work and largecost is normally involved in their control. The installation of rock bolts (LR4), drainage (LR5), or retaining walls (LR6) on asingle house site may be necessary to provide local stability, but are unlikely to withstand the attack of a large storm on abeach or cliff-line.

BUILDING NEAR CLIFFS AND HEADLANDS

Coastal cliffs and headlands exist because the rock that they aremade from is able to resist erosion. Even so, cliff-faces are notimmune and will continue to collapse (Figure 1) by one or other of themechanisms shown on GeoGuide LR4. If you live on a coastal cliff,you should undertake inspection and maintenance as recommendedin LR4 and the other GeoGuides, as appropriate. The top of the cliff,its face, and its base should be inspected frequently for signs ofrecent rock falls, opening of cracks, and heavy seepage which mightindicate imminent failure. Since the sea can remove fallen rocksrapidly, inspections should be made shortly after every major stormas a matter of course. If collapses are occurring seek advicefrom an appropriately experienced geotechnical practitioner.Advise you local council if you believe erosion is rapid or

accelerating.

Building on Coastal Dunes

Any excavation in a natural dune slope is inherently unstable and must be supported and maintained (GeoGuide LR6).Dunes are particularly susceptible to ongoing erosion by wind and wave action and extreme changes can occur in a singlestorm. Whilst vegetation can help to stabilise dunes in the right circumstances, unfortunately a single storm has thepotential to cut well into dunes and, in some cases, remove an entire low lying dune system or shift the mouth of a river.As for cliffs, it is appropriate to observe the effects of major storms on the coastline. If erosion is causing thecoastline to recede at an appreciable rate, seek advice from suitably experienced geotechnical and coastalengineering practitioners and bring it to the attention of the local council.

CLIMATE CHANGE

The coastal zone will experience the most direct physicalimpacts of climate change. A number of reviews of globaldata indicate a general trend of sea level rise over the lastcentury of 0.1 - 0.2 metres. Current rates of global averagesea level rise, measured from satellite altimeter data over thelast decade, exceed 3 mm/year and are accelerating. Themost authoritative and recent (at the time of writing) report onclimate change (IPCC, 2007) predicts a global average sealevel rise of between 0.2 and 0.8 metres by 2100, comparedwith the 1980 - 1999 levels (the higher value includes themaximum allowance of 0.2 m to account for uncertaintyassociated with ice sheet dynamics).

In addition to sea level rise, climate change is also likely toresult in changes in wave heights and direction, coastal windstrengths and rainfall intensity, all of which have the capacity

to impact adversely on coastal dunes and cliff-faces. A Guideline for responding to the effects of climate change in coastalareas was published by Engineers Australia in 2004.

AUSTRALIAN GEOGUIDE LR11 (RECORD KEEPING)


RECORD KEEPING

It is strongly recommended that records be kept of all construction, inspection and maintenance activities in relation todevelopments on sloping blocks. In some local authority jurisdictions, maintenance requirements form part of the buildingconsent conditions, in which case they are mandatory.

CONSTRUCTION RECORDS

If at all possible, you should keep copies of drawings, specifications and construction (i.e. "as built") records, particularly ifthese differ from the design drawings. The importance of these documents cannot be over-emphasised. If a geotechnicalpractitioner comes to a site to carry out a landslide risk assessment and is only able to see the face of a retaining wall, theheads of some ground anchors, or the outlets of a number of sub-soil drains, it may be necessary to determine how thesehave been built and how they are meant to work before completing the assessment. This could involve drilling through thewall to determine how thick it is, or probing the length of the drains, or even ignoring the anchors altogether, because it isuncertain how long they are. Such "investigation" of something that may only have been built a few years before is, atbest, a waste of time and money and, at worst, capable of coming up with a misleading answer which could affect theoutcome of the assessment. Documentary information of this sort often proves to be invaluable later on, so treat it with asmuch importance as the title deeds to your property.

INSPECTION AND MAINTENANCE RECORDS

If you follow the recommendations of the Australian GeoGuides it is likely that you will either carry out periodic inspectionsyourself, or you will engage a geotechnical practitioner to do them for you. The collected records of these inspections willprovide a detailed history of changes that might be occurring and will indicate, better than your own memory, whetherthings are deteriorating and, if so, at what rate. Unfortunately, without some form of written record, all information isusually lost each time a property is sold. It is recommended that a prospective purchaser should have a pre-purchaselandslide risk assessment carried out on a hillside site, in much the same way that they would commission a structuralassessment, or a pest inspection, of the building. If the vendor has kept good records, then the assessment is likely to bequicker and cheaper, and the outcome more reliable, than if none are available. Each site is different, but noting thefollowing would normally constitute a reasonable record of an inspection/maintenance undertaken:

• date of inspection/maintenance and the name and professional status of the person carrying it out

• description of the specific feature (eg. cliff face, temporary rock bolt, cast in situ retaining wall, shallow leach drainsystem)

• sketch plans, sketches and photographs to indicate location and condition

• activity undertaken (eg. visual inspection; cleared vegetation from drain; removed fallen rock about 500 mm diameter)

• condition of the feature and any matters of concern (e.g. weep holes damp and flowing freely; rust on anchor headsgetting worse; shotcrete uncracked and no sign of rust stains; ground saturated around leach field)

• specific outcomes (eg. no action necessary; geotechnical practitioner called in to advise on the state of the anchors;cliff face to be trimmed following the most recent rock fall; leach field to be rebuilt at new location)

A proforma record is provided overleaf for convenience. Photographs and sketches of specific observations can prove tobe very useful and should be included whenever possible. Geotechnical practitioners may devise their own site specificinspection/maintenance records.

Planning Context

Why are we rezoning land at Riverstone East?

Partnerships

• Department of Planning and Environment is leading the

project in partnership with Blacktown City Council

• Governance: Project Control Group (PCG) and Precinct

Working Group (PWG)

• Council’s role:

- Representing local community interests

- Technical input through specialist staff

- Implementation of the plan

What is Precinct Planning

• Assessing suitability of the land for urban development

• Evidence based

• Structure planning - will determine development potential

• Deciding land uses (zoning) & controls (e.g. building size

and height) for urban development

• Co-ordination of infrastructure:

- Road, water, sewer, electricity, telecommunications etc.

Process

4

An important part of the precinct planning process is to engage with landowners to seek their input to the preliminary results of these studies and the constraints and opportunities understood to exist within the Precinct. Figure 1 identifies where the process is up to.

Figure 1 Precinct Planning Process

1.3. Context of the Vineyard Precinct

The Vineyard precinct is located in the Hawkesbury local government area in the North West Growth Centre. The Precinct is bound by Commercial Road to the north, Boundary Road to the east, Windsor Road to the south, and portions of lots to the west (as shown in Figure 2). The Precinct itself is some 8 kilometres from Windsor and is the only Precinct identified for urban development in the North West Growth Centre (refer to Figure 3).

Precinct Planning for the site will need to take into account the character of the precinct due to its interface with rural land surrounding the area, and its close proximity to rezoned areas such as Box Hill & Box Hill Industrial Precincts and Riverstone Precinct. The precinct is around 590 hectares in size and there are currently approximately 272 land owners.

Land uses and specific requirements for the Precinct will be established through the precinct planning process however the North West Growth Centre Structure Plan identifies the majority of the Precinct for urban residential development, including the potential for 2,500 new dwellings for 7,000 new residents.
